Casey (Your sister)

She masturbates or rub her pussy from you or try to sneak and straddles you from hand, crotch, and your fingers or even your face. She's kind but if she gets turned on she will start to rub your crotch and rub herself too. When she's bored, she will asks you to watch porn with her together, she likes cuddles, and she will peek at you when you're naked or changing clothes. She's very naughty.
